SWING.

To all whom it may concern:

Be it known that I, GEORGE W. SoHILLINe, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Swing, of which the following is a specification.

The object of this invention is to devise a novel construction of a double power swing which will start with very little motion and gradually attain a greater height.

A further object of my invention is to construct a power swing wherein the stroke of the swing may be regulated as desired by J the employment of a suitable clutch.

A further object is to devise a novel driving mechanism for a swing so that a slower movement will be imparted thereto at the ends of the stroke.

It further consists of novel means for controlling the swing and novel means for checking the movement thereof as desired.

To the above ends my present invention consists of a novel construction of a power swing which is actuated by frictional driving means and wherein novel means are employed for controlling the movement of the same and also novel means for regulating the stroke of the swing.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illusyrating my invention, I have shown in tie accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a sectional elevation of a swing embodying my invention, the sec tion being taken on line ww, Fig. 5. Fig. 2 is a sectional view of a portion of Fig. 1. Fig. 3 represents a sectional view of a portion of Fig. 1, showing more clearly certain details of construction. Fig. 4 represents a side elevation of one of the friction cones to which the arms of the swing are secured. Fig. 5 represents a sectional elevation of my device, certain parts there- Specification of Letters Patent.

of being removed for the sake of clearness of illustration. Fig. 6 represents a section on line y-y, Fig. 5. Fig. 7 represents a sectional elevation of another embodiment of my invention. Fig. 8 represents a side elevation in detached position of a brake member, seen in Fig. 5. Fig. 9 represents a side elevation of another embodiment of driving gears which may be employed if desired. Fig. 10 represents a side elevation in detached position of one of the friction cones.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates a motor of any desired or conventional type, operatively connected in any desired manner wit-h the driving mechanism of the swing, in the present instance, a belt 2 being provided which is driven by the motor shaft and imparts motion to a pulley 3 mounted on a shaft 4; on which latter is mounted an elliptical or intermittent gear 5 which meshes with a similar gear 6 mounted on a shaft 7. The gear 6 is provided with a slot 8 whereby a connecting rod 9 may be ad justably secured with respect to the slot 8 by means of a bolt or equivalent fastening device 10. One end of the connecting rod 9 is operatively connected with an arm 11 fixedly mounted on a shaft 12 journaled in brackets 13 carried by a cross bar 14 which latter is provided with the side supports 15.

The shaft 12 has mounted thereon four male friction cones 16, 17, 1S and 19, the cones 18 and 19 being keyed to the shaft and provided with double arms 54 and 20, the outer ends of which are preferably enlarged and provided with apertures 21 as most clearly seen in Fig. 3. The aperture 21 has preferably a differential diameter and is adapted to receive a plunger 22 which is provided with a head 23 in order to maintain the same in assembled position and against the head 23 abuts a spring 24, the other end of which is in engagement with an adjustable plug 25 whereby the tension of the spring 24 may be varied as desired. The plunger 22 is preferably provided with an enlarged contact head 26. Since the plunger in one arm is constructed in a similar manner to the plunger in the other arm, I have deemed it unnecessary to describe in detail both of these plungers and the manner in which they are mounted. The friction by means of key ways 27 in order that said cones may have longitudinal movement relative to the shaft.

28 designates the female friction cones which are loosely mounted on the shaft 12, said cones being provided with brackets 29 4 to which the arms 30 are secured which lat- 12 so as to have longitudinal movement thereon, the movement of the block 33 in one direction being limited by means of adjusting screws 34 carried by one of the brackets 13. r

35 designates a friction brake which is loosely mounted on the shaft 12 and is provided with a quadrant 36 which travels within a bracket 37 secured to the side supports 15 and'provided with set screws 38, which engage a bearing plate 39 thereby imparting a desired friction against the quadrant 36, it being noted that the quadrant 36 is provided with laterally extending lugs or contact members 40 with which the arms of the swing co-act.

41 is a clutch member loosely mounted on the shaft 12 and coacting with a clutch member 42 having longitudinal movement only relatively to said shaft, said clutch member 42 being provided with an arm 43 to which may be connected a cord, cable or other desired connection for actuating the clutch while the swing is in motion.

In order to stop the swing, I provide a brake, which, as most clearly seen in Fig. 6, comprises a friction disk 44 with which coacts a friction member 45 suitably fulcrumed and having secured to one end a spring 46, the other end of which is attached to a suitable fixed' point such as the cross bar 14 .suitable material. which engages withthe shaft 12 or an eccentric 50 thereon.

' In the embodiment seen in Fig. 9, I have shown a modified form of driving mechanism wherein I employ two gears 51 and 52,

each of which is provided with a dwell 53,

the connecting rod 9 being secured with respect to the gear 52 in a similar manner to that already described with reference to Fig. 1.

The operation of my device will now be readily apparent and is as follows z-VVhen the motor 1 is started, motion is imparted to the gears 5 and 6 which are preferably constructed in such a manner as to give a slower movement at the ends of the stroke in order to allow the swing to reverse, it being seen by reference to Fig. 1 that this is accomplished by the elliptical or intermittent gears 5 and 6, while in the embodiment seen in Fig. 9 this is accomplished by the employment of the dwell 53. The gear 6 imparts motion to the connecting rod 9 thereby rocking the shaft 12 whereupon the friction cones or drums 16, 17, 18 and 19 impart motion to the friction cones 28 loosely mounted on the shaft and thereby to the swing. After attaining a medium height, the double arms 54 and 20. come into act-ion, increasing the height of the swing and in order to prevent too much jar when the double arms are brought into action I provide the spring plungers 22.

My novel construction of automatic brake becomes operativeowi ng to the contact of the arms on the swing with the members 40 of the quadrant 36, it being apparent that as the swing is in motion one of the arms when it reaches a certain height will contact with the contact member on one side of said arm and the upward movement of the swing will be retarded by the engagement of the friction plate 39 with the quadrant, it being understood that the quadrant 36 will be moved from its normal position and on the return movement of the swing the arm on the opposite side will engage with the other contact member 40 and the upward movement of the swing in a reverse direction will be restricted by the frictional contact with the frictional members 39 against the quadrant 36 so that an automatic friction brake is provided which will' prevent the swing from traveling to an undesired height, it being apparent that the friction of the members 39 against the quadrant 36 may be readily adjusted by means of the adjusting members 38 provided therefor. When the motive power is shut off and it is desired to bring the swing to a stop the rod or cable 47 is actuated, thereby causing the engagement of the friction member 45 with the friction wheel 44 fast on the shaft 12 thereby bringing the shaft 12 gradually to its stationary position.

If the embodiment seen in Fig. 7 is employed it will be seen that this construction embodies the broad principle of my invention, namely the friction drive for the swing and at the same time by employing an eccentric on the shaft I vary the throw of the swing.

It will be apparent that in some cases the double arms 54 and 20 may be dispensed with in which case the swing will not travel as high and it will also be apparent that the form and construction of the friction cones may be varied according to the conditions of each case. It will also be apparent that by means of the friction brake the travel of the swing will be retarded to the desired extent and the friction of the cones may be readily adjusted by means of the set screws 34:, as is apparent.

So far as I am aware I am the first in the art to devise a swing which is provided with frictional means for driving the same and it will be apparent to those skilled in this art that by such a construction the swing itself may be stopped at any time without shutting off the motor or the driving mechanism so that people may get in and out of the swing while the driving mechanism is continuously operating.

It will now be apparent that I have devised a novel and useful construction of a swing which embodies the features of ad vantage enumerated as desirable in the statement of the invention and the above description, and while I have in the pres ent instance shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
